Python 2.7 quick reference

22.8. The print statement: Display output
values

Use this statement to display values on the standard
output stream. General form:

print thing1, thing2, ...[,]

Each thing
must be a string, or a value that can be converted into a
string by the str() function (see Section 20.40, “str(): Convert to str
type”). These strings are written to
the standard output stream, with one space between each
value. A print statement by itself prints
an empty line.
